A Turkish official says a passenger claiming there was a bomb on board tried to divert an Istanbul-bound plane to Sochi, Russia, where the Olympics are kicking off.
Habib Soluk, the Transport Ministry undersecretary, told private NTV television that the plane from Kharkov, Ukraine, to Istanbul, landed safely at Istanbul's Sabiha Gokcen airport.
He says authorities are trying to convince the passenger to give himself up.
News reports say the plane was a Pegasus Airlines flight.
A spokeswoman for the airline declined comment.
